The performance of the distributed coordination function (DCF) of IEEE 802.11 has been shown to heavily depend on the number of competing stations in WLAN. As the number of stations increases, the performance dramatically decreases since the probability of packet collision increases. Due to these reasons, there have been many research efforts to reduce the(More)
This paper describes a dynamic service differentiation scheme based on access category (AC)'s traffic flow for QoS provisioning in the IEEE 802.11 wireless local area network (WLAN). The proposed scheme adjusts contention window sizes by considering the contributions of each traffic instead of each node on the network contention rate. There have been(More)
